A comfortable apartment is not only a pleasant interior and furniture, but also the correct sound insulation. Severe rock behind the wall, crying of children and clatter over their heads can be infuriated. Especially if the walls, floor and ceiling without sound insulation.

What is noise insulation
Reducing the noise level in the apartment by installing special materials on the walls, floor and ceiling are called sound insulation. It must be done if the apartment is in a monolithic house, and the walls are made of a gas block, foam concrete and concrete.
Noise insulation in the apartment can not be done if the apartment building is made of brick. Or if the apartment is small, since the soundproofing of walls, floor and ceiling takes the space. If a small budget is allocated for the repair of the apartment, it should be borne in mind that soundproofing materials are expensive.
Preparation for sound insulation
First of all, it is worth taking the plan of the apartment and calculating whether it is possible to make noise insulation in it. The finish soundproof the space. High -quality multilayer materials can reach 7-10 centimeters with thickness.
If in a room with an area of 20 square meters to make noise insulation of four walls, then the space will decrease by 1.5 square meters. Such a narrowing of the space can violate the interior and the planned arrangement of furniture, remove doorways, sockets and switches.
If noise insulation fits into the plan, then it should be determined in which rooms it must be performed. From external noise, not the whole apartment is sounded, but individual rooms that adjoin the next wall. Usually it is a bedroom, a nursery or a living room.
Important: If the bedroom has a street or a staircase behind the wall, then this wall is no need to sound. It will be enough to make a sound insulation of the floor and ceiling.

The sound in the apartment can fall not only through the walls, but also through the floor and ceiling. The noise insulation of the walls will not help if the noise source is under or above the apartment, especially if it is a shock noise. Therefore, the floor and ceiling also need to be soundproof.
Important: If there is such an opportunity, it is better to agree with the neighbors from above and make them soundproofing the floor. This is more effective and cheaper than to make sound insulation of the ceiling.
Noise is airy, shock and structural.
Air is transmitted through the air and penetrates through the walls, floor and ceiling. For example, these are conversations, barking dogs and music.
Shock noise is a clatter, the movement of furniture, the sound of an elevating elevator and other blows on the surface. Such a sound is transmitted by the floor and ceiling.
Structural noise is a sound that is transmitted by the design of the building and solid partitions. It can include noise from the drilling of walls or the knock of a hammer. In this case, the noise from the first floors can reach the last floors of the building.
Proper soundproofing of walls, floor and ceiling will protect the apartment from different types of noise. The noise level in the apartment for sanitary standards should not exceed 55 decibels during the day and 45 decibels at night. For example, a regular conversation is 45 decibels, and the child’s crying is already 70. If the apartment has walls without sound insulation from a gas block, foam concrete and concrete, some sounds from a neighboring apartment will be heard.
Concrete slabs between floors also poorly stop such a sound as the clatter and the sound of moving or falling objects. Therefore, in order not to hear these sounds, the sound insulation of concrete floors should be made.
Walls with frame noise insulation
Good sound insulation should be built on the principle of a multilayer “pie”. Mineral wool from below, drywall on top. Such sound insulation protects well from air and shock noises. The effectiveness of such a “pie” will increase if it is attached to the wall using a frame. In this case, noise will be better absorbed. Such sound insulation is 7-10 cm thick, reduce the noise level in the apartment by 40-50 DC. The conversations of the neighbors behind the wall, the crying of the child, and the loud barking of the dog will not be heard muffledly.
How to fix: The Texound membrane is installed on the wall (7). It reduces the vibration of the frame, and also absorbs sound. Next, the vibration suspension “SOCHCOPO” (5) is installed. It is screwed to the wall using special vibrations. An iron frame is attached to the vibration suspension (6). In the empty space of the iron frame and between the cells, the noise -absorbing slabs “Stopzvuk” are laid (3). Further, the sealing tape is glued to the entire frame (4). The entire structure is covered with the Texound membrane (2) then, the Acasticgips plasterboard plates are attached to the frame (1). All joints of the soundproof frame are glued with a dumpfer ribbon (8).
Important: Mineral wool is best used to use a density of 60–65 kg per cubic meter. Instead of conventional sheets of drywall, you can use GVL – this is the same drywall, but it is stronger and has better sound insulation. For greater effectiveness, you can use not one, but two sheets of drywall.
Minus: It takes up a lot of space and costs more than analogues. The price of such sound insulation is about 5 thousand rubles per square meter.
Walls with frameless sound insulation
All other soundproofing methods are less effective, but have their advantages. For example, frameless solutions consist of panels that are attached to the wall with dowels and screws. Such sound insulation takes up little space. A room with an area of 20 squares after installing sound insulation will lose only about 0.5 square meters. It is easy to mount it on the walls. Plates are cheaper than frame sound insulation – about 4 thousand rubles per square meter.
Minus: The wall before installing the panels must be made even and with minimal differences. Deviations in values should not exceed 3 mm per square meter.
Noise insulation is worse than that of frame systems. Lai dogs and blows on the wall will be felt stronger than that of frame noise insulation.
Important: In both cases, an electrician should first be carried out, and then install noise insulation. Where there will be noise insulation, it is better not to make sockets and switches. Otherwise, sound insulation will be broken. To make sockets and switches on such a wall, you need to use special sockets. They are more expensive than standard. An ordinary socket costs 20 rubles, and a noise -gap 1.5-2 thousand rubles.
The most budget option for noise insulation is mineral wool, plastered with cement. In this case, mineral wool is attached to the wall, covered with a reinforced net and plastered with cement or gypsum putty. Such sound insulation does not require a special styling technology, it can be done quickly and cheaply. The cost of work with the material reaches about 2.5 thousand rubles per square meter.
Minus: This option of soundproofing will reduce the noise level in the apartment by 10-20 percent. You will not hear conversations behind the wall, but you will clearly hear the cry of the child and barking of the dog.
Floor
The sound insulation of the floor is made under and above the cement screed. When soundproofing under a screed on a concrete base or on a cement screed, if it is already flooded, put a bitumen-drive membrane or basalt plate. Then, on top, everything is poured with a cement screed with a thickness of at least 5 centimeters.
Important: It is better to use a bitumen-inflammatory membrane instead of a basalt slab. It is thinner and protects the apartment not only from noise, but also from moisture. The screed on top of the soundproofing should not be in contact with the wall directly.
Noise insulation under the screed is the most effective option among all other types of sound insulation. Such sound insulation can completely drown out shock and air noises, such as clatter, barking a dog, crying a child and the sound of a TV.
The soundproofing option over the cement screed protects worse from extraneous sounds than under the cement screed. In this case, the soundproof layer is placed on top of the cement screed. To do this, the damping substrate is laid on the base, a soundproof membrane is placed on it, and an enhanced drywall on top. Then a laminate or quartzvinyl is laid for noise insulation. This method can only slightly reduce shock noises. Only soundproof panel slabs will be able to drown out conversations from below and a knock of doors.
Options using soundproofing panels are more effective than substrates, but they are more expensive than the rest of the analogues and raise the base of the floor by an average of 5 centimeters. They are placed on a screed, interconnected, and then a sheet of plywood or GVL is screwed on top. Tiles on such a base cannot be placed, but laminate, linoleum can be.
Ceiling
On the ceiling before sound insulation, electricity should be carried out.
Noise insulation can be frame and frameless. The frame base of the ceiling is made in the same way as at the walls. Mineral or basalt slabs are laid between the frame. Then the entire structure is sheathed with drywall and it is putty with gypsum mixtures.
Important: When installing the frame on the ceiling, vibration suspens, vibrations, dampfer tape and sealant should be used.
Hare solutions protect worse from extraneous sounds than frame. Half -haired solutions include noise insulation slabs. They are attached to the ceiling with screws, and then sheathed additional with drywall. All joints are covered with sealant.
Minus: Such a system will cost more than other systems. The complexity of the installation is comparable to frame sound insulation. The ceiling becomes lower by 5-10 centimeters.
In terms of the price-quality ratio, it is worth using the noise-insulating blanket “Thermosuroisol”. One side of the blanket self -adhesive. It can be glued to the ceiling and fixed with screws and dowels. After you can make the final ceiling coating.
Myths about sound insulation
Some materials are imposed as noise insulation, but they are intended for completely different purposes.
Foam instead of sound insulation
Foam and any of its types are a good insulation, but not sound insulation. Therefore, the use of a foam for the soundproofing of the premises will not give an effect.
Frame for noise insulation made of wood
To make it cheaper, the frame for sound insulation is not assembled from metal on vibration suspensions, but from wood. In this case, the upper layer of drywall is in contact with the wall and the sound is not extinguished, but passes into the room.
Hinged acoustic panels of fabric and wood
Hinged panels made of wood and fabrics will also not give a special effect. These are more decorative elements, not sound insulation.
Errors in soundproofing
Sound insulation is a complex and expensive process. Even because of a small error, you can spend the material and get poor efficiency from work.
Violation of the technology for laying noise insulation
The biggest error in the installation of soundproofing is associated with violation of the technology of laying materials. Each soundproof layer should go in the sequence as the installation rules require. Any changes will worsen the quality of sound insulation.
Savings on auxiliary soundproofing materials
If in the process of soundproofing do not use a damper tape, soundproofing sealant, vibration-insulating suspensions and washers, then the quality of soundproofing will decrease by 40-50 percent.
Using ordinary sockets for soundproofing walls
If the usual sockets are mounted in the nozzle wall, then the effect of soundproofing will deteriorate. The sound will fall into the apartment through the outlets. In order not to violate sound insulation, you need to use soundproofing sockets.
Conclusions
To get rid of extraneous sounds behind the wall, it is quite high quality to make noise insulation of one adjacent wall. There are a lot of soundproofing materials in the market, noise insulation in the form of a “pie” is especially effective. It combines several layers of different materials.
In order for the soundproofing material to work, its thickness should be more than 5 centimeters.
Noise insulation must be done strictly according to technology and use proven materials. Sound insulation hides the space. It should be included in advance in the repair plan
